for andrea mitchell. president obama in a joint news conference with david cameron makes it known that the benghazi probe is nothing but filled with political motivations. >> who executes some sort of cover-up or effort to tamp things down, for three days? so the whole thing defies logic and the fact that this keeps on getting churned out, frankly has a lot to do with political motivations we've had folks who have challenged hillary clinton's integrity, susan rice's integrity. mike mullen and tom pickering's integrity. it's a given that mine gets challenged by these same folks. >> joining me now for the daily fix, chris cillizza, msnbc contributor and managing editor of post politics.com and senior editor and kelly o'donnell. it was a defiant president obama today, let's see he used political circus, sideshow, and no "there" there. if there was any doubt about how the president feels about the benghazi probe coming from capitol hill, i think we now know. >> no question. chuck, contrast that to how he approached the irs story, the question was a two-parter, actually a three-parter.
